Renewable energy, generated from natural resources such as wind, water, sun and biomass, have the potential to supply 100% of the UK’s power. They are non-polluting and are in limitless supply thereby providing us with a sustainable option for our future energy needs.
Generating your own energy from renewables Toggle accordion
Solar power is ideal for urban living since solar energy systems can be easily integrated into the existing structure of a building. Solar energy can be used to provide either electricity or heat.
Solar photovoltaic (PV) systems convert the suns energy into electricity. Contrary to popular belief they do not require direct sunlight to generate electricity and are therefore suitable in our northern climate. Many systems allow the householder to connect a two-way meter so that any excess electricity can be sold to the grid.
Solar thermal systems absorb heat from the sun which can be used to heat domestic hot water. There are two different available types of solar thermal collectors – evacuated tube and flat plate collectors. Evacuated tube collectors are more efficient but also more expensive. A typical solar thermal system, when fitted to a south-facing roof, will supply around 72% of a household’s hot water over a year (a boiler or immersion heater is usually also required during winter). They are probably the most cost-effective domestic renewable energy technology that can be installed in this country, with the shortest payback time.
Ground and air source heat pumps
Ground source heat pumps transfer heat from the ground into a building to provide space heating and in some cases pre-heat domestic hot water. Some electricity is used to power the pump but for every unit of electricity used, 3-4 units of heat are produced, making it an efficient way of heating a building. The system is ideal for new build homes and there are no planning issues given the underground nature of the system. You will need space outside for the ground loop and the heat generated can be linked to existing systems, though it is ideally suited to households with underfloor heating.
Micro wind power
Whilst there is little potential within the St Albans district for large-scale wind turbines, there are many opportunities for small scale domestic turbines, called micro-turbines. These can be integrated into a building by being fitted to the roof or on a mast.
Micro-turbines typically cost from £1,500-£20,000. The effectiveness of micro-turbines is highly dependent on wind speed and the surrounding land-use so are most suitable for properties in a rural location, where there is open exposure free from turbulence and obstructions from surrounding buildings or trees. If you are considering a wind turbine it is advisable to have a professional assessment of wind-speed in the exact location of the turbine over a year.
Wood-fuelled heating systems
Biomass boilers use wood fuel in the form of pellets, chips or logs to power central heating, provide warmth and hot water. This system of heating may either consist of a standalone stove which may also be connected to a back boiler to provide hot water or a wood burning boiler connected to a central heating and hot water system. They do contribute to particulate air pollution so are not a perfect alternative to gas or electricity.
St Albans Solar Streets Toggle accordion
We are working in partnership with (IDDEA) to help home-owners in St Albans install Solar PV panels at a lower than average cost. If you have ever through about solar panels but not been sure where to start, this scheme is for you. We will make sure you get all the assistance you need to discover if solar panels will be effective on your property and what your options are.
For every solar installation completed, a contribution will be made by the installer to a Community Renewable Fund which will then be used to install solar panels on community buildings. This could be anything from £50 upwards depending on the size of the installation. So you can have the double satisfaction of knowing not only did you reduce your own environmental impacts, you have helped to grow renewable energy in your community to!
How do we obtain discounted panels?
- Savings are made through bulk purchasing and by condensing installations which reduces travel times and improves for efficiencies of scale
- By holding group education and awareness-raising sessions, time and costs are minimised
What you can expect
- You will have access to online videos which explain how the scheme works and what the options are
- You will have an opportunity to participate in regular online FAQ events where you can ask questions and discuss the project with other residents
- You will receive a free no obligation survey
- You will then receive a fully costed quote. This will include a 25% reduction on the average cost of Solar PV system, fully installed
- You will be provided with advice on optional extras to maximise savings such as batteries, water heaters, and monitors
- You will also receive advice on general household energy efficiency and ways to reduce bills and carbon emissions

Grants and funding for renewable technologies Toggle accordion
Renewable Heat Incentive (RHI): The Domestic RHI provides a financial incentive to households to install heat-generating renewable technologies such as biomass boilers, air or ground source heat pumps and solar thermal systems. Payments are made on an annual basis according to an estimation of the amount of heat generated. An essential criterion for joining the Domestic RHI is that the renewable heating system heats only a single domestic household, which is evidenced by obtaining an Energy Performance Certificate (EPC). For further details visit the Ofgem website. In cases where the renewable heating system is in commercial, public or industrial premises (including hospitals, schools and organisations with district heating systems), application may instead be made to the Non-Domestic RHI.
Planning requirements Toggle accordion
The planning rules have been simplified to make it easier for those wishing to install renewable technology. Please refer to the Planning Portal website for information on the rules. Special considerations are likely to apply to listed buildings or those sited within the green belt or conservation areas. Within conservation areas inconspicuous positions for installations are encouraged however this may mean that solar panels cannot be placed on the south facing slope of the roof.
Buy renewable energy Toggle accordion
If you want to see provision for renewable energy improved in the UK, choosing a green energy tariff is a great start. Choose a tariff where the energy supplier can demonstrate that for every unit of energy you purchase, they will fund equivalent renewable resource, 'additional' to their statutory obligations. Switching is free and there are websites to help you do this. We suggest you use an Ofgem accredited switching service. Remember to tell your old supplier why you’re switching!
